黑龙江省628例尿路结石成分分析

Urinary stone composition of 628 cases in Heilongjiang Province

目的：了解黑龙江省尿路结石成分构成情况,分析本地区泌尿系结石成因,为临床治疗和预防提供理论依据。方法：采用红外光谱法对628例尿路结石标本进行化学成分分析,研究分布特征。结果：尿路结石患者男女比例为2.88∶1,上、下尿路结石患者比例为4.98∶1,41~50岁年龄段患者比例最高,结石单一成分以草酸钙检出率最高,为20.4%,混合成分主要以1-水草酸钙（或1-水草酸钙＋2-水草酸钙）＋碳酸磷灰石为主,占54.8%,感染性结石及尿酸结石仍占有较大比例。结论：红外光谱法分析泌尿系结石,有助于了解结石成因,对临床治疗及预防有重要意义。

Objective：To investigate the composition of urolithiasis in Heilongjiang province and to analyze the causes of urolithiasis formation and to provide the reference for the treatment and prevention of urolithiasis.Method：628samples of urolithiasis from our hospital were collected and analyzed with infrared spectroscopy,and the basis of relevant clinical data was analyzed.Result：Among 628 cases of urolithiasis,the ratio of male and female was 2.88∶1;the ratio of the upper urinary tract calculus and the lower urinary tract calculus was 4.98∶1.Most patients with high prevalenceaged from 41 to 50years old.Single component stones were given priority to calcium oxalate calculus（20.4%）;the mixed stones were given priority to calcium oxalate monohydrate and dehydrate plus carbonate apatite（54.8%）.Infection stones and uric acid calculus havesome proportion.Conclusion：Infrared spectroscopy method for analyzing the composition of urolithiasis is significant for the treatment and prevention of urolithiasis.
